Problems solved by technology

[0004] However, when cutting the flexible display blank with a rigid organic substrate, the laser will also damage the hard organic substrate while cutting the flexible display blank into multiple flexible display substrates, making it soften, deform or decompose, resulting in hard The organic substrate cannot be reused, which causes a lot of waste of the rigid organic substrate and also increases the production cost of the flexible display substrate

Embodiment Construction

[0024] The manufacturing method of the flexible display substrate and the manufacturing method of the flexible display panel according to the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] like figure 1 As shown, an embodiment of the present invention provides a method for manufacturing a flexible display substrate, including:

[0026] Step S101 , fabricating a cut-off filter film 2 on the rigid organic substrate 1 , the cut-off filter film 2 is used to reduce the transmittance of the cutting laser. The cross-sectional schematic diagram after forming the cut-off filter film 2 on the rigid organic substrate 1 is as follows figure 2 As shown, exemplary, the rigid organic substrate 1 is a glass substrate, because the glass substrate is transparent, easy to manufacture, and cheap. Of course, other qualified substrates can also be selected, which is not limited here.

[0027] The working principle of ...

Abstract

The invention relates to the field of a display technology, and especially relates to a manufacturing method of a flexible display substrate, and a manufacturing method of a flexible display panel. The manufacturing method of the flexible display substrate comprises the following steps: manufacturing a cut-off filtering film on a hard organic substrate, wherein the cut-off filtering film is used for reducing the transmittance of a cut laser; forming a flexible substrate on the cut-off filtering film; preparing display patterns on the flexible substrate to form a flexible display pallet board; and cutting the flexible display pallet board by use of the cut laser to form the flexible display substrate. According to the method, the arranged cut-off filtering film can prevent the hard organic substrate from damage caused by the cut laser, protects the hard organic substrate, enables the hard organic substrate to be repeatedly utilized for multiple times and accordingly reduces the manufacturing cost of the flexible display substrate. The manufacturing method of the flexible display substrate can be used for preparing the flexible display substrate.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for manufacturing a flexible display substrate and a method for manufacturing a flexible display panel. Background technique [0002] In recent years, display panels made of flexible display substrates have attracted extensive attention because they can realize flexible displays. Existing flexible display substrates are formed by cutting a large flexible display blank according to preset cutting lines by means of laser cutting, and a large flexible display blank can be cut into multiple small flexible display substrates. [0003] The principle of laser cutting the flexible display blank is to use laser light to irradiate the cutting line on the flexible display blank, so that the flexible display blank in the area where the cutting line is located is melted or vaporized, so as to achieve the purpose of cutting. However, due to the large size and softness of the flexibl...
